ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the 
valves.

on a cold engine, at room temperature.
 When the valve clearance is to be measured 
or adjusted, the piston must be at top dead 
center (TDC) on the compression stroke.

NOTE:
 The thickness “a” of each valve pad is 
marked in hundredths of millimeters on the 
side that touches the valve lifter.
 Since valve pads of various sizes are origi-
nally installed, the valve pad number must be 
rounded in order to reach the closest equiva-
lent to the original.
c. Round off the original valve pad number 
according to the following table.
EXAMPLE:
Original valve pad number = 148 (thickness 
= 1.48 mm (0.058 in))
Rounded value = 150
